The race format of a Backyard Ultra is quite simple. You have to run a 6.7km loop within the hour, every hour, until there is only one race participant left. Runners drop out of the race for 3 main reasons:

The most important thing is to know that the big yards are only done by a few athletes, and the heart of the sport is regular people achieving personal goals. Don't be intimidated to think that the 3 or 4 lap people do not belong with the 30 or 40 lap runners. Everyone is running to do their best and every victory is celebrated by all.

In the immediate vicinity of Gevgelija, along the regional road Thessaloniki - Skopje, there is the Negorci spa. It is located at the foot of Mount Kozhuf, at an altitude of 50 meters, three kilometers from Gevgelija and six kilometers from the border with Greece.

In the vicinity of the spa there are three natural springs with large reserves of underground hot water. Its thermal mineral springs, around which the spa facilities are built, occur on the right side of the Vardar River, at the foot of the Kozhuf mountain, between the villages of Mrzenci and Negorci at an altitude of 60 meters. In the Spa region there are two waters - Hot Bath with a temperature of 40 degrees and Cold Bath with a temperature of 38 degrees.

This is the only bath in the country that also has thermal mud, which is located about 500 meters south of the thermal springs. It is fine-grained, almost black with light-dark particles of plant origin with a temperature of 34 to 36 degrees, making it very suitable for pleoid therapy.
